Here the verb is used in the meaning of still knowing something or recalling something (as opposed to actively not forgetting something, see DWOTD Onthouden). Don’t forget to use the reflexive pronoun!

– "Herinner je je je oma nog?"("Do you still remember your grandmother?" The three "je’s" are deliberate: the first is the subject, the second the reflexive pronoun, and the third the possessive pronoun.)
